- the lenses of the two modules are identical.
- the low cutoff line of the beam produced by each lens is advantageously located below the cutoff line of the code beam, in particular at about 1%, to avoid any risk of an unlit strip in the road beam.
- Each lens has an outline preferably located within a circle of 3 cm in diameter.
- each lens has a substantially square contour having a side of about 2 cm.
- Each concave mirror advantageously comprises a cutout located in an area behind the corresponding lens to prevent the formation of parasitic reflected rays which, after reflection on the mirror, pass through the lens instead of passing by.

- the illumination of the central area above the strip is achieved with a paraboloid-shaped concave mirror or a half paraboloid, in the case of a module consisting of a half corresponding to about one half of a paraboloid.
- the paraboloid, or the part corresponding to a half paraboloid is either focused near the bottom of the emitter, or focused in the center of this emitter but turned upward around a horizontal axis perpendicular to the optical axis of the projector and containing the focus.
- the paraboloid, or half paraboloid has a focal length of a quarter of the width of the module lens.
- the paraboloid, or the half paraboloid is unfocused or focused and has a focal length of between 3 and 7 millimeters
- FIG. 1 drawings can be seen a schematic front view of a lighting device E according to the invention for the left side of a vehicle.
- the right-side lighting device is deduced by symmetry relative to the vertical longitudinal median plane of the vehicle.
- the lighting device E comprises a code 1 projector capable of giving a conventional cut-off light beam.
- the trace of this beam on a screen orthogonal to the optical axis of the headlamp is represented by a zone 2 ( Fig. 2 ) of illumination limited in the upper part by a horizontal cutoff line 2a extending to the left from the optical axis, and by a straight line 2b inclined at 15 ° on the horizontal, rising from left to right and then extend with a horizontal part.

- Each module comprises, as a light source, at least one light-emitting diode or LED 7 ( Fig. 7 ) preferably rectangular flat emitter, mounted on a vertically disposed printed circuit board 8.
- Each of the modules 5, 6 has a lens 9 ( Fig. 7 ), arranged in front of the LED 7.
- the lens 9 is calculated to generate a wide beam 10 shown in FIG. Fig.2 by its trace on a screen orthogonal to the optical axis.
- the beam 10 has a low cut 11 substantially rectilinear horizontal, relatively clean, and an upper edge 12 which it is not necessary that it is clean and straight.
- the angular height of the beam 10 between the lines 11 and 12, seen from the projector corresponds to an angle whose tangent is of the order of 5%.
- the lateral extent of the beam 10, expressed as a tangent of the opening angle, is at least ⁇ 20% on either side of the optical axis Y.
- the low cutoff 11 is preferably located slightly below the cut 2a of the code beam to avoid any risk of an unlit area.

- the illumination levels in the rectangular band corresponding to the beam 10 are relatively high, at least 10 lux.
- Such an example of lens 9 is described in the European patent EP1762776 .
- the shape of the lens 9 may correspond to the lens represented in FIG. EP1762776 . It should be noted that in the example shown in figure 6 in the present application, the lens 9 is positioned upside down vertically with respect to the lens shown in FIG. EP1762776 .
- the lower cut 11 must not be too low to prevent a cut line dragging on the road, a short distance in front of the vehicle, creating a line of contrast annoying to the driver.
- the low cut 11 is located about 1% lower than the cut line 2a of the code beam, the conditions are satisfactory.
- At least one concave mirror 13 is used to recover light from the LED 7 and complete the rectangular illumination band provided by the 9.
- the mirror 13 is located behind the lens 9, in the direction of propagation of the light, and the LED 7 is located in the vicinity of the focal point, or pseudo-focus, of the mirror 13.
- Each lens 9 has a contour which is preferably located within a circle 3 cm in diameter.
- the outline of each lens 9 is substantially square, with a side of about 2 cm.
- the lenses 9 may be made of molded plastic.
- the lens 9 is molded in one piece with vertical bars 14, 15 respectively extending upwardly and downwardly from the middle of the upper and lower horizontal sides of the lens 9.
- the bars 14, 15 are provided for fixing (not shown) of the lens to the mirror 13.
- the concave mirror 13 of the first module is provided to provide illumination above the strip 10 produced by the lens 9, in a median zone 16 above the optical axis Y.
- the illuminated area 16 by the mirror 13 is illustrated on Fig. 3 by isolux curves.
- the mirror 13 can be a dish unfocused, or focused down the emitter of the LED 7, with a very short focal length, for example between 3 and 7 mm.
- the mirror 13 makes it possible to extend the average levels of illumination upwards in the region of the optical axis. However, there is a lack of illuminance volume sideways, on both sides of the area 16 illuminated by the mirror 13.
- the second module 6 is designed to compensate for this lack and to create an illuminated area 17 schematically on Fig. 4 , corresponding in a way to "rabbit ears".
- Zone 17 has two lateral lifts separated by a central zone in valley corresponding to zone 16.
- the concave mirror 19 of second module 6 is determined to give this illumination zone 17.
- Each module 5, 6 is equipped with the same light source formed by an LED 7.
- the LEDs 7 of the two modules are installed on the same printed circuit board, which simplifies manufacture.
- a cutout 13a, 19a is made in each mirror 13, 19, in the area behind the lenses 9 to remove the reflective portions of the mirrors that could be the source of such reflected light parasite .
- the optical axes of the two modules 5, 6 are substantially parallel, the fusion of the beams being effected at infinity, that is to say about 25 m in front of the lighting device.
- the lenses 9 are located in front of the mirrors 13, 19 whose apparent contour surrounds the lenses 9.
- the mirrors 13, 19 are limited by concave curved edges corresponding to the intersections of the surface of the mirror by horizontal and vertical planes parallel to the mirror. optical axis.
- the rays reflected by the mirror 13 do not pass through the lens 9 and do not cause parasites in the illumination beam.
- the rays coming from the mirror 13 provide illumination in the central part of the beam corresponding to the zone 16.
- the light rays i3 coming from the LED 7 and falling on the rear face of the lens 9 are refracted along r3 rays which give the rectangular strip 10.
- Module 6 giving with its concave mirror 19 a beam 17 according to two rabbit ears.
- Fig. 8 shows an alternative embodiment in which the two lenses 9 of the modules 5 and 6 are connected by a transverse bar 20 substantially halfway up the two inner vertical edges of the lenses 9, which can be molded in one piece with the bar 20 .
- Fig. 10 illustrates, on a screen graduated in% on the abscissa and ordinate, the L9 network of isolux curves obtained with a lens 9 while the LED 7 is on.
- the beam corresponds to a substantially rectangular strip of light with a cut or a low pseudo-cut placed in the vicinity of the horizontal cut of the code.
- the strip extends over a width of at least 40% ( ⁇ 20% on either side of the optical axis) and over a sufficient height of approximately 5%, in order to reduce the perception of the cutoff of the Beam code in operation raised (width), despite the rapid movements of the body (height).
- the focus of the mirror is horizontally centered on the transmitter, and vertically offset at a distance less than or equal to half the height of the transmitter (the height of the rectangular transmitter of the LED 7 is referenced "hs" in figure 7 ).
- the coordinates of the focal length of the mirror 13 correspond to an abscissa and a zero ordinate and a coast less than 0 (center of the emitter) and greater than or equal to -hs / 2 (the lower edge of the transmitter).
- the Fig. 11 shows the network C13 of isolux curves obtained with the concave mirror 13 of the first module 5 and with the lens 9 corresponding.
- the mirror 13 has a focal length of 3 mm, a focus located in [0,0, -hs / 6], where hs ( Fig.7 ) is the height of the rectangular emitter of LED 7.
- the isolux curves on Fig. 11 show, on each side, a substantially rectangular extension corresponding to the ends of the strip 10.
- the isolux are formed by substantially concentric convex curve arcs ranging between about -8% and + 15%, with a "deadly" effect in the upper central portion 21.
- the so-called “deadly” effect corresponds to a highly concentrated beam, of relatively elliptical shape (of substantially vertical major axis), which decreases sharply laterally in intensity.
- the driver of the vehicle thus observes a lighting on a narrow portion of the road, in front of him, and a strong darkness all around, so that the driver sees only in a very narrow channel, as if he observed the road to through a murderer.
- In the lower part there is a zone 22 of overlap with the beam code.
- Fig. 12 is a network C19 of isolux curves obtained with the mirror 19 of the second module 6. Above the horizontal line of cut of the code beam, we find the two ends of the rectangular strip produced by the lens 9. The isolux curves in their upper part have, on both sides of the optical axis, lifts 23, 24, separated by a central valley 25. The lifts 23, 24 are reminiscent of "rabbit ears" and are placed on the side and other of the central illuminated area of Fig. 11 .
- Fig. 13 illustrates the C3 network of isolux curves obtained by the fusion of the C13 and C19 beams of the two modules 5 and 6.
- the bottom aperture 13a of the mirror does not correspond to significant flux losses if this aperture is substantially located in the focal plane of the paraboloid 13, given the hemispherical emission indicator of the LEDs. Ensuring such a characteristic for a given lens size amounts to constraining the choice of the focal length value of the paraboloid 13. Indeed, to have in these conditions an opening greater than or equal to the size of the lens, it will be necessary to take a paraboloid focal length greater than or equal to one quarter of the lens size (ie, one-quarter on its side when the lens is square). This is a constraint only preferential, to avoid parasitic radiation. The most efficient optimization, a maximum of reflection and a minimum of parasitic radiation, corresponds to a focal length equal to a quarter of the size of the lens.
- the beam given by such a system illustrated by the network of isolux curves of Fig. 11 , contains the desired cut-off beam and the height desired in the vicinity of the axis, as well as the overlap area at the bottom, but has an undesirable "lethal" effect which is compensated by the second module 6.
- the second LED 7 is identical to that of the first module, as is the lens 9.
- the beam shown on Fig. 11 is that of the first module 5 with a mirror 13 of paraboloid type with focal length of 3 mm, and focus in [0,0, -hs / 6], where hs is the height of the rectangular emitter of the LED 7.
- the flow efficiency of the total corresponding to the beam shown on Fig. 13 is 66% of the flow of the LEDs 7. This efficiency takes into account the cutouts 13a, 19a of the mirrors as well as notches for fixing the lenses, but not the external mirror of the projector.
- Fig. 14 illustrates the network of isolux curves of the road beam R obtained with the lighting device according to the invention while the beam code has been raised by 2.2% and the complementary projector is in action.
- Another solution would be to have a module with a first paraboloid-type mirror on one side of the vehicle and another module with a second mirror giving the two "rabbit ears" on the other side of the vehicle.
- This solution appears less good because the settings will be delicate for a correct beam fusion and, even if the settings are made correctly in the factory, they may be altered later.
- the code beam is asymmetrical. If the road beam is obtained without using a raised code (mechanical lifting of the code of about 1.5 °), aim the maximum of the ball of the complementary road beam along the optical axis.
- the complementary road beam will be aimed approximately 1.5 ° lower than the horizontal on the point called "50 V" (maximum of the beam code).
- the mechanical bearing of the assembly (code + complementary road) is controlled with generally the same angle.
- the modules of the complementary projector are therefore particularly compact while being efficient, ensuring an intensity high luminous, and comfortable, thanks to a high luminous flux and the light suitably placed.
